1 (Jlaim. (CL l 43) This invention relates to a cooling or refrigerating'device, and has for one of its objects the production of a simple andefiicient cooling device which is provided with Suitable. cold storage compartments in close relation to an ice containing compartment in which icecompartment is mounted a water cooling co'iI leading to a water containing tank, which water cooling tank also contacts the ice compartment to maintain an efficient cooling temperature within the cold storage compartments as well as within the water cooling tank.

A further object of this invention is the production of a simple and efiicient sanitary cooling device wherein the contents in the cold storage compartments thereof is not touched by the ice in the ice containing compartment and further, the ice containing compartment remains intact and is not disturbed or opened as the doors to the cold storage compartments are opened.

Other objects and advantages of the present invention will appear from the following specification and claim.

In the drawings:

Figure 1 is a top plan view of the device;

Figure 2 is a front elevational view thereof;

Figure 3 is a longitudinal sectional view taken on line 33 of Figure 1, certain parts being shown in elevation;

Figure 4 is a longitudinal sectional view taken on line 44 of Figure 1, certain parts being shown in elevation;

Figure 5 is a transverse sectional view taken on line 5-5 of Figure 4 certain parts being shown in elevation;

Figure 6 is a fragmentary vertical sectional view taken on line 6-6 of Figure 2, the door being shown in elevation.

By refering to the drawings in detail, it will be seen that 10 designates the casing or housing of the cooling device. The wells of the casing or housing 10 are preferably of insulating material. An ice containing compartment 11 constituting a primary cooling compartment is preferably placed centrally within the casing or housing 10. The wall of the compartment 11 is preferably formed of thin galvanized or sheet metal of a suitable type. A secondary water cooling or cold water compartment 12 or tank completely surrounds the ice containing compartment 11 and directly abuts the front and rear faces of the compartment 11, as is shown in Figure 5. The compartment 12 is spaced laterally from the opposite sides of the ice containing compartment 11, thereby defining a cold storage compartment 13 upon one side of the compartment 11 and a second cold storage compartment 14 upon the opposite side of the compartment 11. The water cooling compartment 12 also extends under the compartments 11, 13 and 14, as shown in Figures 3, 4 and 5. A faucet 15 is connected to the water cooling compartment 12, as is shown in Figure 5 for drawing off water for drinking purposes. A further drain 16 is provided for the water cooling compartment 12 for the purpose of flushing and cleaning the same of sediment and the like when desired. The compartment 12 is inwardly spaced United States from: the casing 1 0 to provide a dead air space 10a there between.

"The front portion of the cold storage compartment 14.

is provided with an access 'p'ening' 17,. which is normally closed by a suitable door 1 8. The cold storage compartment 13 is provided with a similar" access opening which is normally closed by a suitable door 19. "A lid 20 normally closes the access opening. 21- in thef' top of the ice containing compartment 11, as shownin Figure 3. The top of each cold storage compartment 13 and i4 is closed asis alsoshown in Figure 3.

' A coil 22, preferably of copper tubing is arranged within the ice containing compartment 11 in close contact with: the inner face of the wall ofthe com-partment 11- the convolution of the coil providing a chamber for receiving a cooling. agent'such as" ice 23. The ice is adapted to be placed in this: chamber through the access opening '21. An inletipe 24 is secured to, the top of the-coil 22 and a vertical outlet pipez's is connected to the bottom or the coil 22. The outlet pipe 25 is provided with lateral extensions 26 and 27. The extension 26 continuously empties into the top of the water cooling compartment 12 at one end of the casing 10 and the extension 27 continuously empties into the top of the water cooling compartment 12 at the opposite end of the casing 10, as is shown in Figure 4. A drain off or circulation pipe 28 also communicates with the top of the compartment 12 for drawing off water from the compartment 12 under pressure when so desired.

From the foregoing description, it should be understood that the water is first cooled by passing through the coil 22. The water then passes up through the pipe 25 and into the water cooling compartment 12 by means of the pipes 26 and 27. Since the ice containing compartment 11 is located centrally of the casing 10 and the cold storage compartments 13 and 14 are located intermediate the ends of the compartment 11, the contents of the compartments 13 and 14 will be cooled by the compartment 11 as well as by the ends of the compartment 12.

In other words the compartment 11 will transmit its temperature to one side of each compartment 13 and 14 and the ends of the compartment 12 will transmit the temperature to the opposite or outer sides of the compartments 13 and 14.

Since the device provides a compact coiling element surrounding the ice within the ice containing compartment, and the water cooling compartment surrounds the cold storage compartment with the cold storage compartment between the ice containing compartment and the water cooling compartment, convenient and efiicient spaces are provided where suitable articles of food or bottles of beverages may be cooled to proper temperature prior to dispensing the contents thereof for consumption.

Furthermore, cold storage areas are provided which are sanitary, since nothing in the cold storage compartments 13 and 14 may be touched when the doors are closed. The ice containing compartment 11 is not disturbed when the doors are opened to remove the contents of the compartments 13 and 14. It will be noted by considering the drawing that the cold storage compartments 13 and 14 are practically surrounded by the cold water compartment or tank 12, the water being initially cooled by passing through the coil 22. The ice in the compartment 11 also cools all adjacent areas, since the compartment 11 is only separated from the compartments 13 and 14 by means of a thin galvanized iron or other metal wall. The water first passes through the coil 22 where it is cooled by the ice and is further cooled or continuously cooled erated apparatus requiring upkeep and repair is involved in the present invention.

It is obvious that the device may not only be used as above defined, but may be used to advantage most economically to cool anunlimited quantity .of beverages, such as beer, by passing the beverage through the coil 22, the tank 12 and then dispensing the beverage through the faucet 15. A source of supply may be connected to the inlet pipe 24. A point of remote discharge may, if desired, be connected to the pipe 28.

It should be understood that certain detail changes may be made in the structure illustrated without departing from the spirit of the invention, so long as these changes fall within the scope of the following claim.

Having described the invention, what I claim as new is:

A cooling device of the class described comprising an insulated casing, a primary cooling compartment having a relatively thin wall in said casing, a secondary liquid cooling compartment comprising a tank surrounding said primary compartment, said primary compartment having front, rear and bottom walls directly contacting the secondary liquid cooling compartment, the secondary compartment being inwardly spaced relative to said casing thereby defining a dead air space therebetween, a cold storage compartment upon opposite sides of said primary compartment and intermediate and contacting the primary and secondary compartments, a liquid cooling coil lining the primary compartment, the primary compartment being adapted to receive a cooling agent within the convolutions of said coil, a liquid feed pipe connected to one end of said coil, a liquid outlet pipe connected to the opposite end of said coil, means connecting said liquid outlet pipe of said coil to said secondary compartment for delivering precooled liquid from said coil directly to said secondary compartment to supply cool water from the coil to said secondary compartment, and a drain ofi means for said secondary compartment.
